Sarah-Jane Summers (don't forget the "Jane") and her partner Juhani Silvola playing Scandinavian folk sublimely. I can hear some sul ponticello in there. Cool video too.
Sarah-Jane taught me for a few year and is one of the reasons I am now a composer. She has studied a Masters at Oslo. They are working on some new material so it will be interesting to see what they do next. In the meantime check out this video.
